Reading in data from PDF files to servlets

Im working on a rather large project & all was well, I was reading in data from a comma deliminated file, extracting what i needed & away I went...great, OK so today they tell me they are going to a different format...all of the inbound information will be in pdf format. Does any one know of an API or anything I can plug into 1.4 (Non enterprise) to be able to read & extract data from a pdf. Im running on a Linux box, with Resin....all help would be DEEPLY appreciated.
